Roney Posted July 10, 2019 Share Posted July 10, 2019 Hi. I am in need of information on which board to use for data acquisition of an electrochemical sensor. I'm using the amperometry technique. The sensor provides an electrical current signal in the range of 20 nanoAmperes up to 8 microAmperes. What kind of data acquisition board would you recommend me? How to read current signals so low? Thank you. Link to comment Share on other sites More sharing options...
jpeyron Posted July 11, 2019 Share Posted July 11, 2019 Hi @Roney, I do not believe we have a Pmod that would meet your parameters. Our PmodISNS20 is current sensing but is +/- 20A with a 12bit ADC. This would not meet your needs. I believe the Allegro ACS722 IC on the PmodISNS20 could be made to meet your needs in a custom PCB. best regards, Jon Link to comment Share on other sites More sharing options...
